Application filed September 22,

2' 0 all to 7mm zf may concern:

Be it known that I, CLAUDE B. DAVlS, a citizen of the United States, residing at Richmond, in the county of Henrico, State of Virginia, have invented certain new and useful improvements in Clothesringing Attachments for Washtubs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to clothes wringing attachments for wash tubs and it has for its object to provide an article about which may be fastened the fabric to be wrung and which will hold securely to the usual sheet metal wash tub against the strains that are incident to the wringing operation, it being a further object of the invention to provide an improved means for operating the mov able clamping jaw, which will be not only highly etlicient but economical of its manufacture and not subject to radical deterioration.

In the drawings:

Figure 1 is a perspective view showing the article in use upon a tub.

Fig. 2 is a perspective view of the attachment, a portion'of a wall of a wash tub being shown in sectional perspective, to illustrate the manner in which the U-shaped cam lever is associated with the movable jaw and the hook plate to actuate the movable jaw.

Fig. 3 is a side elevation of the attachment, with the near side of the U-shaped clamping jaw removed.

Fig' 4: is a horizontal section taken in a plane to include the pivot of the clamping lever.

Referring to the drawings, the present attachment comprises a hook made of a rod or bar of metal that is bent to form the hill 5. the shank 7 and the connecting bend or bight 6. The shank stands horizontal and at its end it is herein shown as bent at right angles away from the bill but in the same plane with the remainder of the hook and it is flattened at its side remote from the bend of the hook to lie snugly against the inner arm 8 of a U-shaped clamp which includes alsothe outer arm 9 at the bend or bight 10. The flattened portion of the hook Specification of Letters Patent.

is shown at 11 and is secured to the inner arm of the clamp in any suitable manner.

The spacing of the arms of the clamp plate is slightly more than the thickness of the bead 13 that is formed by bending outward over a wire the upper edge or the wall of the usual sheet metal wash tub let. Transversely of the inner face of the outer arm 9, is secured a pivot pin 15 that projects at both ends beyond the side edges of the arm and serves to pivotally mount the arms of the U-shaped clamping lever 16, which arms embrace the arm 9 of the Ushaped clamp. The pivot pin engages the arms of the clamping lever near to their upper edges and the free ends of the arms of the clamping lever are rounded to constitute cams 17.

Between the ends of the arms of the clamping lever and the arm 8 of the U- shaped clamp, is disposed a movable clamping jaw that includes a central clamping portion 20 and the outwardly bent end portions 21 that lie slidably against the outer faces of the arms of the clamping lever. These end portions 21 have each an enlarged opening 22 in which is received the corresponding end portions of the pivot pin so that while this clamping jaw may be moved up and down and toward and away from the arm 8 of the U-shaped clamp, it cannot drop from between the arms of the U-shaped clamp.

The parts are so proportioned thatwhen the article is disposed over the wall ofa wash tub 14 the bead 13 of the tub will be received against the bight 10 and above the movable clamping jaw. If the clamping lever is then swung with its outer end downwardly its cam edges will engage the central portion of the movable clamping jaw and will urge it against the corresponding face of the tub wall. The clamping lever exerts its greater pressure before it is swung all the way down as will be noted from the cam shapes and when downward movement of the lever is completed. the pressure of the lever is reduced to a slight degree and the resiliency of the curved tub wall serves to hold the lever yieldably in such lowered or active position.

It will be noted that in the structure described, a secure clamping operation is obtained While the structure is not only eX- tremely durable but is very cheap of manufacture, two features essential to the commercialization of an article of this character.

What is claimed is:

1. A tub engaging clamp for clothes wringers including spaced arms and a connecting bight portion, a movable jaw disposed between the arms and having spaced end portions between which one of the arms is embraced and with which arm they are loosely connected, and a Ushaped clamping lever straddling and pivoted to said last mentioned arm and having terminal cam faces disposed to engage and move the clamping jaw in the direction of the other arm, one of the arms having a clothes receiving member.

2. A tub engaging clamp for clothes wringers including spaced arms and a connecting bight portion, a movable clamping jaw disposed between the arms, a lever under the influence of which the clamping jaw is movable into clamping relation to one of the arms and a single means carried by the other arm for pivotally connecting the cam lever and slidably connecting the clamping jaw therewith.

3. A tub engaging clamp for clothes wringers including spaced arms and a connecting bight portion, a movable clamping jaw disposed between the arms and having spaced parallel end portions having openings therethrough, a cam lever under the influence of which the clamping jaw is movable into clamping relation to one of the arms and a pivot carried by the other arm and on which the lever is pivoted, the pivot extending loosely through the openings of the end portions of the clamping jaw.

In testimony whereof, I affix my signature, in the presence of two witnesses.
